The reference size is 1 oz, approximately 31.1035 g or 1 troy ounces. For coins, this comparison refers to the 1 oz edition; fractional sizes are separate variants.

Calculate the price per gram
Divide the delivered price by declared fine-gold weight. Illustrative arithmetic, not a market quote: at 100 GBP per gram of fine gold, 31.1035 g gives a hypothetical metal value of 3,110.35 GBP. A real offer adds a premium and delivery. If the stated weight is gross weight, calculate fine-gold weight first.
A troy ounce and a metric gram are both used in UK bullion offers. Compare the same fine-gold amount in pounds; a coin’s face value is not the amount you pay or its metal value.
Buying and delivery · UK
For a United Kingdom purchase, compare the delivered total in pounds sterling. A euro or US dollar quote is not directly comparable until conversion, delivery and any import costs are included.
Confirm UK delivery coverage and insured handover. A seller dispatching from outside the UK can have different shipping and import terms. Keep tax questions separate from a product’s name and check current HMRC guidance for the exact item and your circumstances.
